SPECIFICATION forming part of Letters Patent No. 3l3,308,dated March`3, 1885.

Application filed September 4, 1881. (No model.) p

Be it known that I, JACOB FOLGER, a citizen of the United States, residing at Toledo, in the county of Lucas and State of Ohio, have invented new and useful Improvements inv Refrigerators, Ice Boxes, and Cool Storage Rooms, of which the following is a specification.

Thisinvention relates to improvements in refrigerators, and has for its object to provide a novel construction and combination of devices whereby a large space can be subjected to a low temperature by a comparatively small consumption of ice, and also whereby a comparatively dry cooling room or apartment is provided.

The refrigerator will be first described in detail, and the improvements afterward pointed out in the claims, reference being made to the accompanying drawings, illustrating my invention, in which- Figure 1 is a longitudinal vertical section of theice-room and cooling-roorn complete. Fig. 2 is avertical cross-section of the ice-room and cooling-room complete. Fig. 3 is ahorizontal section taken through the ice-room on the line m x.

Similarletters refer to similar parts throughout the several views.

The entire exterior walls of the rooms 'are constructedv of an outer and inner casing, a a',

connected by studding, leaving a six-inch space, A, which isfpacked with sawdust or shavingsand in portable boxes, especially, this six-inch space A, I fill with several walls of straw-boardor other kinds of pasteboard separated by cleats, covering the joints in the straw-board, making air tight apartments, and also a much lighter box or refrigerator. In the interior `of the room thus formed, a skeleton ice-box, B, is supported on joists E E E, Src., placed crosswise of the room and passing through the interior casing, a,on which a close door, N, is laid, leaving a space, O, on each side and one end six inches wide and on the remaining end twelveinches wide, for cold-air passages C C C and O to theroom K below, the twelve-inch wide passage C forming the front of the cooling-room. The close iioor N has a slight incline toward the 5o front or twelve-inch space C. The close door N has a covering of galvanized iron, I, turned up two inches high on the two sides and the end next to the narrow cold-air passages C C C, andturned down at the front end in lthe wide coldg-airpassageC to carry the drip of 55 -thewater on the floor, I into a trough, H, which connects with a drain-pipe, T. Strips of twoby-two-inch lumber are placed lengthwise on the iron floor I, on which is laidarough openjointed floor, F, to receive the ice l?. Studding V V V, 8vo., are placed vertical in the coldair passages C C C 0, to which are secured slats b b b b, &c., forming a grating to retain the ice P and the drip of water from it within the limits of the iron' floor I. The edges of 65 the slats b b b, &c., have an inward and downward bevel to carry the drip in. The circulation of cold air through the cold-air passages O C C C is governed by sliding doors S S S, &c., on the sides between the joists E E, &c., and on the ends or back and front by hinged fall-doors D D, or by sliding doors S S, &c., as on the sides, as convenience may require. By this means the circulation of cold air into the cool storage-room K below may be perfectly controlled by the opening or closing of the doors more or less, as desired. In the same manner I construct one or more rooms below the cool storage-room K, leaving air-passages through the floor of the room K and along the walls of the same, and control the flow of cold air into the same by means of doors, as described above, and as indicated by the darts on the drawings. By this construction I am able to maintain a nearly even tem- 8 5 perature in my cool storagerooms ranging from 40 to 42.

A door, L, and window W may be arranged at any place convenient to enter and get light into the cool storage-room K, and in the same manner a door may be arranged above for the purpose of lling the ice-box B.

By a suitable connection onto the drainpipe T, I bring the water out at a convenient place and have a good supply of cold drinking-water.

For the convenience of construction and moving from place to place, I secure together the sides, ends, and several parts of my rooms and boxes by means of screws and bolts.

IOO

I do not broadly claim a skeleton ice-box located above a refrigerating or preserving chamber and separated therefrom by a ilooring so that the air circulates from the ice to the preserving-chamber through openings at the sides of the ice-box and in the flooring.

at the opposite sides and ends of the ice-box,

a closed iiooring under the ice-box to create a preserving-apartment thereunder, and independentlyadjustable doors at the lower ends of the vertical air-passages to control communication between the latter and the preserv' ingapartment, substantially as described.

2. In a refrigerator, the combination of a casing, a skeleton ice-box comprising longitudinal slats and supported in the upper portion of the casing to create vertical air-passages at opposite sides of the ice-box, the vertical studs arranged in the side air-spaces between the longitudinal slats and the casing, a closed floor under the ice-box to create a preserving-compartment thereunder, and a series of doors arranged at each side of the ice-box for controlling the lower ends of the vertical air-passages, substantiallyr as described.

8. In arefrigerator, the combination of a casing, a skeleton ice-box comprising slats and arranged in the upper portion of the casing, a series of studs arranged vertically at each side and end of the ice-box and creating vertical airpassages'at all sides and ends thereof, a closed flooring under the ice-box to create a preserving-compartment thereunder, an open ice-supporting floor above the closed floor, a series of doors along each side of the ice-box, and doors at the ends thereof for controlling tlie communication of the lower ends of the vertical airpassages with the preserv ing-compartment, substantially as described.

4. In a refrigerator, the combination of the preservingfapartment, the skeleton ice -box above the same, the vertical air-passages at each side and end ofthe ice-box, the series of doors along each side of the ice-box, and the doors at the ends ofthe latter for controlling communication between the lower ends of the air passages and the preserving compartment, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
